5927443800 Implement full support for parsing primary expressions. We can now parse 
all of health and voronoi (ignoring directives).  We only get 409 lines into
176.gcc though because we don't have binary operators yet:

Parsing 176.gcc.llc.s:409: unexpected token in operand list
	movsbl	_arityvec+1(,%edi,8), %eax
	      	         ^

bb07cd38e3 Testcase for (llvm-gcc) 73873. Usually 
std::pair<double, float*>
is 16 bytes on darwin-powerpc, but not always.

db7860aa40 Teach ScalarEvolution how to analyze loops with multiple exit 
blocks, and also exit blocks with multiple conditions (combined
with (bitwise) ands and ors). It's often infeasible to compute an
exact trip count in such cases, but a useful upper bound can often
be found.

8426522d55 Fix this code to correctly handle loops with multiple exits. Until 
now, this hasn't mattered, because ScalarEvolution hasn't been able
to compute trip counts for loops with multiple exits. But it will
soon.

89e17d02b1 stub out parser for asm files. Change invariant on lexer to always 
print its error message when it returns an asmtok::Error token.
Compute a proper error code for llvm-mc in 'lex' mode.  Add new
-as-lex option to enable lexing mode (vs parsing mode).

580eecebbd change TLS_ADDR lowering to lower to a real mem operand, instead of matching as 
a global with that gets printed with the :mem modifier.  All operands to lea's 
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this.  There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).

This also makes the use of EBX explicit in the operand list in the 32-bit, 
instead of implicit in the instruction.

12ba79a2b7 eliminate the "call" operand modifier from the asm descriptions, modeling 
it as a pcrel immediate instead.  This gets pc-rel weirdness out of the

19fc691c16 Start implementing translation of MachineInstr to MCInst. Next 
step is to make tblgen generate something more appropriate for MCInst,
and generate calls to operand translation routines where needed.
This includes a bunch of #if 0 code which will slowly be refactored into
something sensible.
